#### Step 2: Solve the Challenge Equations
The challenge provides the numbers: 9, 3, 5, 4. We need to choose any 3 of these numbers to complete each equation.

1. Equation 1: \( \_ + \_ - \_ = 6 \)
- Try different combinations:
- \( 9 + 3 - 6 = 6 \) (but we only have 9, 3, 5, 4)
- \( 9 + 5 - 8 = 6 \) (but we don't have 8)
- \( 9 + 4 - 7 = 6 \) (but we don't have 7)
- \( 5 + 4 - 3 = 6 \)
- \( 5 + 4 = 9 \)
- \( 9 - 3 = 6 \)
- Solution: \( 5 + 4 - 3 = 6 \)

2. Equation 2: \( \_ - \_ + \_ = 8 \)
- Try different combinations:
- \( 9 - 3 + 2 = 8 \) (but we don't have 2)
- \( 9 - 4 + 3 = 8 \)
- \( 9 - 4 = 5 \)
- \( 5 + 3 = 8 \)
- Solution: \( 9 - 4 + 3 = 8 \)
